New Class D amplifiers

Indeed, functionality is higher in the sense user has more options in how to connect the amp to a DAC, be it built in or external.

But my understanding is that at the time of developing their GaN amp Peachtree  was solving for how to make that level of amp performance available at a lower price point. And they realized they could do without the analog to digital conversion needed inside the GaN amp. It follows their approach should deliver a given sound quality at a lower price point vs competitors with analog inputs, at the cost of flexibility in inputs. It remains to be seen how GAN 1 compares to other amps in the same price point, though. But I can see use for such an amp and find the concept appealing 

I don’t understand why Roon requires having your amp on all day, but putting that aside, going from A all the way to D strikes me as somewhat extreme for one who is used to the Pass. Why not look into a good A/B first? 

The modded GAN1 is close sonically to my CODA #16 amp. The CODA has the first 100 watts class A and has 150 total at 8. It doubles to 2 Ohm though the Class A likely goes down with Ohms. It is a very elegant sounding amp but with massive power. Too much power for my KEF LS50 Metas. I get a bit of ear fatigue because the #16 puts out a bit too much bass out of the LS50 Meta (without a sub). 

The modded GAN1 is ALMOST as good power wise as the CODA #16. That extra bass on the #16 is nice, but not for long periods in my small room.

I use the GAN1 in my office and the CODA #16 sits idle (will be used in a much bigger room later).

I recently bought a Audiophonics HPA-S400ET Sparkos Edition, Class D, Purifi, 2 x 400 watts @ 4 ohms / 2 x 200 watts @ 8 ohms amplifier.  I am very happy with it.  Take a look at the reviews on Audio Science Review.

In Conclusion!  I have gotten an Orchard audio Starkrimson Stereo Ultra.  I've been very happy with this amp, and will not try to repeat the positive reviews it's received. It was primarily by chance that I selected this unit because I got it at a very good price Used.  I still have my pass labs, but I'll probably look to sell that in the near future.

My next quandary is selecting a good preamp, I'm using a Schiit Freya S  that seems to work well , but I'm really not sure what's the best choice.  That's another story...

I use Freya+ with Starkrimson monoblocks.

Whenever I use different tubes, it change tones.

I can make it sound fuller or sharper depending on vintage tubes.

Fortunately, I have more than 80 diffferent kinds of 6sn7 and variants.😀
